Description
Technical Field
The utility model relates to an air purification field, concretely relates to tuber pipe formula stationary electrode air purification device.
Background
Air contains small amounts of free ions due to radiation friction and the like, and it is not possible to fully charge dust particles in dusty air with these free ions alone. Therefore, two basic conditions are required for separating dust by using static electricity, namely, an electric field for charging the dust exists; the second is the presence of an electric field that separates the charged dust particles.
Under the action of the electric field, free ions in the air move towards the two poles, and the higher the voltage and the higher the electric field strength, the faster the movement speed of the ions is. As a result of the movement of the ions, a current is formed between the electrodes. At the beginning, there are fewer free ions in the air and less current. When the voltage rises to a certain value, ions near the discharge electrode obtain higher energy and speed, and when the ions strike neutral atoms in the air, the neutral atoms are decomposed into positive and negative ions, and the phenomenon is called air ionization. After air is ionized, the number of ions moving between the electrodes is greatly increased due to an interlocking reaction, which is expressed by a sharp increase in the current between the electrodes (called corona current), and the air becomes a conductor. After the air around the discharge electrode is fully ionized, a light blue ring of light is visible around the discharge electrode, which is called corona. Therefore, this discharged wire is called a corona electrode.
At a distance from the corona electrode, the electric field strength is small and the velocity of the ions is small, where the air has not been ionized. If the voltage is further increased, the range of air ionization (corona) is gradually expanded, and finally the air in the interelectrode is completely ionized, and the phenomenon is called electric field breakdown. When the electric field is broken down, spark discharge occurs, and the electric dust collector stops working. In order to ensure the normal movement of the electric dust collector, the range of corona is not too large, and the corona is generally limited to be near the corona electrode.
Since the negative ions have a higher moving speed than the positive ions, the negative corona can generate a higher corona current and its breakdown voltage is much higher at the same voltage. Therefore, in an electric dust collector for industrial gas purification, a negative corona electrode having high stability and capable of obtaining a high operation voltage and current is generally used. An electric dust collector for air intake purification of a ventilation air conditioner generally adopts a positive corona electrode. This has the advantage that less ozone and nitrogen oxides are produced.
The dust particle charging is the first step of the electric dust removal process. There are two different charging mechanisms within an electrodeionization device. One is that ions make directional motion under the action of electrostatic force and collide with dust particles to charge them, which is called electric field charging. Another is that the diffusion phenomenon of ions leads to a dust particle charge, called diffusion charge. Dust particles with aerodynamic equivalent diameter larger than 0.5 μm are mainly charged by an electric field; dust particles with aerodynamic equivalent diameter less than 0.2 μm are mainly diffusion charged; both dust particles having an aerodynamic equivalent diameter of 0.2 to 0.5 mu.
When the electric field is charged, ions are charged through collision with dust particles, an electric field opposite to the external electric field is formed around the dust particles along with the increase of the charges on the dust particles, the field intensity of the electric field is stronger and stronger, and finally the ions cannot reach the surfaces of the dust particles. At this point, the charge on the dust particles has reached saturation.
The electrostatic dust removal technology has a good purification effect on particles with large aerodynamic equivalent diameters, can effectively kill bacteria, almost has no reduction in performance after cleaning, but cannot purify gaseous pollutants, and a metal dust collecting plate has no corona discharge part, and a polar plate is easy to accumulate a large amount of charges.
